HOLDER FOR GLOBES.

Application filed August 27. 1924 Serial No. 724,395.

To all whom it may concern: I

Be it known that I, ALBERT J. D. OHM, a citizen of the United States,and resident of New York city, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in Holders forGlobes, of which the following is a specification.

My invention relates to holders for globes, especially for globes usedin connection with electric lamps.

The object of my invention is to secure holding means that automaticallyadapt themselves to variations in the size of the globe to be held, areresilient so that they adapt themselves to expansion and contraction ofthe globe due to the changes in temperature thereof, provide effectivelocking means to prevent dislocation of the globe from jar or otheraccidental cause, and per mit ready removal of the globe only by apredetermined manual operation.

My invention will be hereinafter specifically described and thenclaimed, and reference will now be had to the drawings form ing a partof this specification, wherein there are illustrated the preferredembodiments of the invention, but it is to be understood that thestructural elements thereof can be varied or changed, as to the size,shape and manner of assemblage without departing from the spirit andscope of the appended claims.

In the drawings, Fig. 1 is a section of the globe holder and globe.

Fig. 2 is a bottom View of the globe holder.

Fig. 3 is a detail of the locking spring.

In the drawings, the globe holder 1, has a depending flange or apron 2,to which is attached an adjustable locking spring 3, fastened at 4.There are two or more U- shaped springs 5 attached to the apron byrivets or other fastening means 6, said springs being curved in at theends to afford a slidable contact with the lip 10.

When it is desired to insert the globe 7 into the globe holder 1. thelooking spring 3 is raised to uppermost position as indicated in Fig. 3in solid lines. The spring 3 is checked in an intermediate upwardposition, by contact with the apron, as at 11, thereby preventing thespring from snapping against the globe and breaking the same.

The globe may then be inserted into the holder and the upper lip 8thereof contactsmally hold the globe. Thus the globe cannot be removedor shaken loose unless the spring? heretofore described.

The locking spring? has an offset, as at 12, which permits adjustabilitybetween the looking spring 8 and the apron 2. This permits play of thespring, to adapt itself to expansion and contraction. of the globe, dueto the change in temperature, as well as to take care of any variationsin the outer diameter of the lip of the globe to be placed in thefixture, without the necessity of special adjustment of the holdingmeans.

Should the globe receive a jar or blow that would cause the globe tomove and if tightly held, as in present practice, it would tend to breakat the points of contact, thereby falling, with consequent injury topersons thereunder. By my invention, thelocking spring 3 adapts itselfto the globe with sufiicient play to prevent the breaking at the pointsof contact but when the globe is moved sufficiently so that there isdanger of its falling, the abutment 12 of the spring 3 contacts with theapron 2, at 13, and by thus abutting against the inner surface of theapron offers severe resistence to the further downward. mbvement of theglobe, thereby completely locking the globe 7 in the holder 1.

Having described my invention, what I regard as new and desire to secureby Letters Patent is:

1. A holder for globes comprising a body portion, spring supports withinsaid body portion and a locking spring secured at one end within saidbody portion and with its other end free and projecting through a slotin said body portion, said free end of said spring having aconfiguration to provide a lip for supporting the globe, and a yoke tostraddle the body portion adjacent said slot whereby said spring may bepositively held in globe supporting position.

2. A holder for globes comprising a body portion, bow-shaped,volute-ended, centrally secured spring supports within said body israised and the globe released as portion, and a locking spring, saidlocking spring being adapted to be alternatively moved into and out ofglobe engaging position.

' A holder for globes comprising a body portion, bow-shaped,yolute-ended, spaced apart spring supports Within said body portion, anda locking spring, said locking spring being adapted to be alternativelymoved into and out of globe engaging posi. tion, and held engaged in anintermediate upwardposition and releasable means for positively holdingsaid locking spring in globe engaging position.

i. A holder for globes comprising a body portion, spaced apart, springglobe supports, each comprising a flat strip of spring material, bentbow-shaped and ith vo lute ends and secured at substantially the centerof one of its sides to said holder, and a looking spring, said lockingspring being adapted to be alternatively moved into and out of globeengaging position,

5. A holder for globes comprising a body portion, apair of spaced apart,spring globe supports, each comprising a flat strip of. spring material,bent bow-shaped and With volute ends and secured at substantially thecenter of one of its sidesto said body portion, and a locking spring,said locking spring having one end secured to said body portion, theother end being free, said free end projecting through a slot in saidholder and having a configuration to provide a lip to support the globeand a yoke to straddle said body portion adjacent said slot'whereby saidlocking spring may be positively held in globe engaging position andwhen so held forming with said spring supports a tripoolal globesuspending frame substantially unyielding to stresses in the directionof the axis of said body port-ion.
